Overview
The LV8771VH is a PWM current control stepping motor driver. It is ideally suited for driving stepping motors used in
office equipment and amusement applications.
Features
• 1 channel PWM current control stepping motor driver.
• IO max = 1.5A
• Output on-resistance (High side : 0.6Ω ; Low side : 0.4Ω ; total : 1.0Ω ; Ta = 25°C, IO = 1.5A).
• Micro step mode can be set to full-step, half-step (full torque), half-step, and quarter-step mode.
• Built-in thermal shutdown circuit.
• No control power supply necessary.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
